This guide provides an overview and description of the line modules (LMs), switch route
processor (SRP) modules, switch fabric modules (SFMs), and input/output adapters
(IOAs) available for the Juniper Networks E120 and E320 Broadband Services Routers.
NOTE: A release may support multiple versions of a module or IOA. For
information, see Software Compatibility in JunosE System Basics Configuration
Guide, Chapter 6, Managing Modules.
Table 1 on page 3 lists the modules and IOAs supported by the router.
This guide also contains the following appendixes:
IOA Protocol Support on page 49
Module and Slot Combinations on page 73
Module Name Cross-Reference Information on page 77
Product Reclamation and Recycling Program on page 79

LM-4 Line Module
ES2 4G LM
Module label
Not applicable
Number of ports
First supported: 7.0.1
Software release
176 W maximum
Acts as frame forwarding engines for the physical interfaces
Responsible for processing data traffic
Pairs with IOAs to process data from different types of network connections
Description
FFA ASIC
Type
Supports a line rate of 128–byte packets on IOAs
The 100–Gbps switch fabric allocates 3.4 Gbps of overall bandwidth to each regular
line module slot and 10 Gbps of overall bandwidth to each of the turbo slots (slot
2 and slot 4).
The 320–Gbps switch fabric allocates 10 Gbps of overall bandwidth to each line
module slot. The line interface on the ES2 4G LM when installed in a 320 Gbps
fabric configuration is 3.9 Gbps; you can achieve this rate with random packet sizes
in the range 64–1518 bytes or a mixture of packet sizes that represent Internet mix
traffic (IMIX).
See JunosE System Basics Configuration Guide, Chapter 6, Managing Modules for
more information.
